Thanks Daniel. Yes, this is a touchscreen with B logo. Now, how do I change the BIOS mode please? Attached are screenshots of the current HP info re Boot, BIOS, and UEFI. BIOS_Boot.zip Regards, Glenn

Thanks. That confirms there is no EDID coming from the screen, so Linux has to guess about the signalling method. Turns out you're not the first to encounter this bug: https://bugs.freedesktop.org/show_bug.cgi?id=97822 So the good news is the hardware is not faulty but just unusual. One user

Wayland versions done. Again, the edids.bin would not attach as it was empty. I have already made various changes to the display under Wayland. All successful, although only in top half of the screen. Regards, Glenn Stewart On Wed, Jan 20, 2021 at 1:29 PM Glenn Stewart wrote: > Thanks

Thanks Daniel. BIOS Update was done under Windows/HP Tools before I installed Ubuntu. xrandrv.txt is attached. edids.bin would not attach, as it was empty. I tried various display settings, which all worked, but within the top half of the screen. Regards, Glenn Stewart On Tue, Jan 19, 2021

I would also try the latest BIOS update from HP, but you need to have Windows installed to do that :( https://support.hp.com/au-en/drivers/selfservice/swdetails/hp- eliteone-800-g2-23-inch-touch-all-in-one-pc/769/swItemId/vc-262067-1 -- You received this bug notification because you are a

[Bug 1906086] Re: DIsplay is limited to top half of the screen

Hi Glenn, That first screenshot in comment #17 is most telling. It shows the BIOS screen is rendered half right and half wrong. So given some of the problems persist in the BIOS screen (when no OS is running) AND in Windows 10, I think it's likely the screen is faulty and needs replacing. But

Hi Daniel. I have installed Ubuntu over Win10. I have enabled Ubuntu on Wayland. Everything works - LAN/WAN, Audio, Video, WiFi, Bluetooth, Printing, Mail, software updates, etc. It's just that it is still squashed up into the top half of the screen. What else should I be doing please? Regards,

Re: [Bug 1906086] Re: DIsplay is limited to top half of the screen

I did not want to actually install Ubuntu. I wanted to be able to run it and see how it has progressed since I last used 12.04 from 2012 till 2016 on 3 x machines that were formerly Win XP. In summary then, my hardware is suspected to be the issue, and if I want to progress to see if the Wayland

[Bug 1906086] Re: DIsplay is limited to top half of the screen

OK. You would need to install Ubuntu before you can choose Wayland. But it's not guaranteed to fix things. And if you see related problems in Windows 10 then it sounds like the hardware is faulty :( Maybe not badly faulty... if the problem is just incorrect timing info in the monitor's EDID.

Hi Daniel. Here is the screenshot of the start up options. There is no 'Ubuntu on Wayland' option available to me at start up. I have tried each option, without success at this point. Windows is still affected. Hard to show as the bottom half "haze" is very light today. [image: image.png]

Next time you boot Ubuntu, please try not only 'Ubuntu on Wayland' but also different screen resolutions in Settings. I would like to know if the problem is specific to the native mode of the LCD panel or happens in other modes too. It sounds like this might be a hardware issue, especially if

Thanks Daniel. Screenshot attached. I am back in Win10 right now, which also became affected by the "hazy bottom half" of the display, although the full screen displayed behind the haze (just hard to read). Will need to try booting again from the stick, to see the option for Wayland. Cheers
